Abstract
Forty-nine patients with cervical spine fractures were identified among 160 patients who underwent CT of the cervical spine for blunt trauma. Although there was a high index of suspicion on the plain film interpretation, as well as a large percentage of false positives, many fractures were found on CT that were not suggested, even in retrospect, on the plain radiographs. Of the 136 fractures ultimately identified in these patients, CT detected 135 (99%) while only 64 (47%) were seen or suspected on the initial screening radiographs. At first glance, this might appear to discredit the plain films as a screening device. However, most of these "occult" fractures occurred in vertebrae that had been identified as probably fractured in other parts, for example, pedicle fractures found in vertebrae initially suspected of harboring only a vertebral body fracture. Most of the remainder of the uncovered fractures were in vertebrae immediately adjacent to ones that were initially identified as fractured. Indeed, of ...
